IMPROVEMENT m BRICK-KILNS.

Specification forming part of Letters Patent No. 190, I 32, dated May 1, 1877; application filed October 7, 1876.

To all whom it may concern I Be it known that l, HENRY DIOKSON, of Homestead, in the countyAlleghen'y and State of Pennyslvania, have invented a new and useful Improvement in the Construction of Fire-Arches of Brick-Kilns; and I do hereby declare that the following is a full and draft is obtained toward and at the center of the kiln.

To enable others skilled in the art to make and use my invention, I will proceed to describe its construction and operation.

In the accompanying drawings, which'form part of my specification, Figure 1 is a longitudinal section of the fire-arch of the kiln. Fig. 2 is a transverse section at line 3 of Fig. 1.

The fire-arches of the kiln are constructed in the usual manner, excepting that the crown is increased from the mouth toward the center of the kiln, as indicated at A B G, whereby the draft is gradually increased in each of the compartments A B O, which results in an equalization of the heat throughout the kiln, thereby burning the brick in all parts of the kiln with uniformity.

Having thus described my improvement, what I claim is'- a In a brick-kiln, a series of arches, A B (3, increasing in depth from the outside to the center of the kiln, substantially as herein described, and for the purpose set forth.
